SUSPENDED COT.

Application led March 27, 1916. Serial No. 86,974.

To all whom it may concern.'

Be it known that I, JOSEPH H. WITT- MANN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Suspended Cote; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures 'of reference marked thereon, which form a part of this specification.

My invention relates to a folding bed or cot, and more particularly to a bed for use by tourists or as an emergency bed for residences or hotels; the principal object of.

the invention beingfto provide a device of this character which may be completely suspended from a single vertical support, the wall of a building, a tree, or the like, or from the single support and from the ground.

In accomplishing this and other objects of the invention, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawing, wherein Figure l is a perspective view of a suspended bed constructed according to my invention, and illustrating its mounting on a single wall support.

Referring more in ings 1 2 designate the inner and outer end bars of the bed, and 3, canvas or the like, which connects the end bars and forms the carrying body.

detail to the draw Fixed to the inner end bar 1 are hooks 4:, j

which are adapted for taking'into eye-bolts, or the like 5, on a wall or other vertical support 6 to carry the inner endv of the bed when the latter is erected and which are substantially S shaped to hold the bar against vertical displacement as well as support the inner end of the bed.V If preferred, the hook may be Xed to the wall and the screw eyes on the bar.

Also fixed to the rear end bar are spreader arms 7 which are more than half the length of the bed, and Xed to the opposite end bar 2, are tension bars 10, that are adapted for engagement by the inner ends of the arm to provide adjustment for the bed, and.

to permit compensation for stretch of the canvas body by locating the latch in proper sockets.

The bed is usually provided with two spreader arms and two tension bars, one of the arms being located at each inner corner vof the bed and one ofl the bars at each outer corner thereof in order to afford the support at the longitudinal edges of the bed. It is apparent, however, that for an exceptionally wide bed, the arms and Vbars and their connecting parts may be duplicated as often as may be necessary to provide subst'antal support, or a single arm and bar may be used for a single bed.

In order to suspend the bed at the outer end, I provide the tension bars 10 with hanger cables 12, the lowerpends of which are connected with the free ends of the bars 10 and the upper ends of which are supported from hooks,.or the like 13, on the supporting wall 6; the upper ends of the cables being preferably provided with links la, any one of which may take over a hook 13 in order to provide further adjustability of the support and compensation for stretch y of the body material.

As there is considerable strain on the spreader arms 7 when there is weight on the bed, that might tend to buckle the arms, I preferably provide each cable l2 with a bifurcated lower end and locate the divided strands 15-15 on opposite sides of the arm to hold the latter against buckling.

In order to hold each spreader arm to its tension bar, I Iprovide the arm with a link 17, which is adapted to take into a notch 18 in the under edge of the tension bar, and in order to lock the spreader arms to their relative tension bars, I provide each arm with a .link 20, which is adapted for taking into one of a number of notches 21 in the under edge of the tension bar, and when preferred can be provided with a latch 22.

In the drawings I have illustrated what may be termed a double bed,icomprising the two sets of spreader arms and tension bars, with the tension bars supported by the cables from the wall 6 at points above the eye-bolts.

When a bed constructed as described is not in use it may becollapsed and folded into a relatively `small space, as the flexibility ofthe canvas or other material will permit the spreader arms and tension bars to fold onto each other.

When the bed is to be erected, assuming that the supporting' wall is provided with the eye-bolts 5 and the hooks 13, the hooks on the inner supporting bar are located in the eye-bolts, the cable hangers supported from the hooks 13 and the lower ends of the spreader arms 7, seated upon the bars 10; the arrangement being such that the bed willl be supported 'in a horizontal plane. With the bed so arranged the inner end is supported directly from the wall and the outer end` from the same wall but from a, higher elevation, because of the connection of the outer'end of the bed with the hanger cables through the tensionbars, andby reason of the abutment of the tension bars against the spreader arms, the compound leverage tending to stretch the canvas when a weight is placed'on the bed, because of the tendency of the tension bars to fulcrum on the ends of the spreader arms.

Any stretch of the canvas may be com-1 pensated for by readjustment of the spreader arms in the tension bar sockets and in the link support of the cable on the wall hooks.

Should the bed'be intended for a continued use without being taken from its mounting, the lock 20, may be utilized as it effects a substantial connection between the tension bars and the spreader arms, although if 'the bed .is used for touring, or the like, when it is to be taken down after a single night7s`use,'the locks need not be utilized.

If so desired the cables 12 may be dispensedl with andthe ends of the tension bars supported directly from the ground, as with this arrangement vdownward movement of the inner ends of the tension bars is resisted as e'ectually as by the overhead support. In either case the inner end pivots on the standing support and the tension bars on the spreaders so that the inclination of the bed is determined by the point of contact of the tension bars with the spreader arms.l

I-Iaving thus described my invention, what IV claim as new therein, and desire to secure by Letters-Patent, is
